26 Claims.

My invention relates to warp knitting machines, and more particularly to the arrangement of a beam or an assembly of sectionaljbeams in a warp knitting machine.

An object of my invention is to provide a connection of a] beam or an assembly of sectional beams with parts of a warp knitting machine of such a construction, that, during the procedure of the inserting of a beam or an assembly of beams intofa warp knitting machine, the beam or assembly of beams may be constantly held in a substantially horizontal position.

Another object of my invention is to. improve upon the connection of the brake end of a beam or assembly of beams with the beam brake and supporting means of a warp knitting machine as now ordinarily made.

A further object of my invention is to improve upon the construction of an assembly of beams for use in a warp knitting machine as dinarily made. y 7

My invention consists in certain novelfeatures of an assembly of sectional beams and a construction for the connection of a beam or an assembly of beams with parts of a warp knitting machine as will be. fully described hereinafter.

tion will be apparent from the following disclosure of several embodiments thereof.

In the accompanying drawings are:

ing member 54 is clamped on thebrake end mem-' brake I8 is arranged on the frameend: member IB'for subjecting the right hand top assembly 20 of three sectional beams 22 to acertain braking action during the operation of the warp "knitting machine. Theftwo top assemblies 20 and 20' of beams 22 are arranged in alignment with each other. The warp knitting'machine may alsoreceive two similar assemblies 24- and' 24' *of sectional beams 22, which may be subjected to a braking action by beam brakes 26 mounted on the frame end member'sof the machine. I

'I'hearrangement and support of the top assemblies 20 and 20 of beams in the warp knitting machine s ne same as that of the lower assemblies 24 and 2d", and furthermore, the connections of theleft hand assemblies 2|] and 24 with parts of the warp knitting machine substantially correspond to the connections of the right hand assemblies 20 and 24 with corresponding parts of the warp knitting machine. Therefore, a detailed description of the left hand top assembly 20 of sectional beams 22 andits connections with parts of the Warp knitting machine issufiicient for afull disclosure of my invention. 1

Asbest shownin Fig. 3, ,the setof sectional beams 22 of the assembly 20 iscarried by an assembling member generally indicated by 28. Said assembling member 28 consists of ,a tube-like member 39, a hollow coupling. member .32 and a hollow cylindrical brake end member 3 4. The

coupling member 32 and the brake end member 34 inserted into theop'enings at the ends of the tube 30 are connected with the latter by screws 36 and 38.

The coupling member 32 of the assembling member 28 has a cylindrical portion 40 for engagement with a roller bearing 42 arranged in the intermediate member IA of the frame of the Furthermore, the coupling member 32 has claws 44 for engagement with recesses 46 in a corresponding couplingmember .32 of the assembling member 28' of, the

assembly 20' of beams 22. A cylindrical pin 48.

insertedinto the bore 5110f the coupling member 52. 48, extends into the bore 50 of the coupling member 32 when the assemblies 20and' 20' of beams are mounted in the warp knitting machine.

The brake-end member 34 carries at its free end a splitconnecting member 54 havinga slot The connectber 34 in a predetermined position by means of a screw 58, which is in engagement with a groove 80 of the brake end member 34 and is threaded into a threaded bore 82 of the connecting member 54. The connecting member 54 is provided with three threaded bores 68 at its side facing the setof beams 22. Adjustable setting screws 88 are threaded into said three bores 88. A ring I is loosely arranged on the brake end member 34 between the heads of said setting screws '88 and the first beam 22 of the set of beams; The setting screws 88 may be adjusted in such a posi tion that they contact the ring and urge the set of beams through the medium of said ring 10 against a flange I2 arranged on the coupling member 32. Thus, the set of 'beams may be frictionally connected with the assembling member 28 for a rotation thereof when the beams 22 are rotated by the yarn drawn on? from the beams during the operation of the knitting machine. The above described connection of the set of beams with the assembling member, 28 takes care of slight differences in the width of the beams, the

connecting member 54 is always in the same position on the brake end member 34 of the assembling member 28. The connecting member 54 is provided with an annular groove 14 for the reception of two gear segments 18 and 18 at its side facing the frame end member I2. The gear se ments I6 and I8 may be attached to the connecting member 54 by means of screws 80. As best shown in Fig. 1, said gear segments I8 and I8 are arranged for meshing engagement with a pinion 82 connected with a drum 84 of the beam brake I8 through a shaft'85 journalled in a suitable bearing mounted on the frame end member I2.

As best shown in Fig. 3 a iournal 88 forming a part of a slidable cylindrical supporting member 88 may be engaged with a needle bearing 90 mounted in the opening 92 at the end of theho1-- low brake end member 34. The lidable sup ing member 88 is in the shape of a rod having a groove 94 for engagement with the end 95 of a screw 98 threaded into a threaded bore 98 of the frame-end member I 2. Therefore, the supporting member 88 may be displaced in the direction of its longitudinal axis, but it cannot participate in the rotation of the assembling member 28. A safety latch I00 is swingably, mounted on a cylindrical shoulder I02 of a screw I04 threaded into a threaded bore of the frame end member I2. When' the slidable supporting member 88 isin the position for engagement with the brake end member 34 of the assembly of thebeams 22, the swingable safety latch may be brought into engagement with a recess I06 on the member 88 for holding same in its position, as shown in Fig. 3.

In order to make the assembly 20 of beams ready for use, the connecting member Y54 and the ring 10 are removed from the assembling member 28. Now, the set of sectional beams 22 may be arranged on the assembling member 23 by shifting same over the brake end member 34 towards the flanged coupling member 32. Then,

' the ring 10 is arranged on the assembling mem- I ber 28 and placed against the head of the first beam 22, whereupon the connectin member 54 After a disengagement of the safety latch I00 from the recess I08 by swinging same around the shoulder I02 of the screw I04, the shiftable supporting member 88 is moved in left hand direction as viewed in Fig. 3, until the end 93'of the groove 94 abuts against the projecting nd I 95 of the screw ,98 and the end of the journal 88 is in theposition 88 shown in dash and dot ring 10 so as to urge the set of beams against the flange 12 of the coupling member 32. The

. assembly 20 of beams thus prepared may be inlines. As may be gathered from Fig. 3, the distance between the end. of the journal 88 in the position 88" and the intermediate frame member I4 is larger than the distance between the end of the brake end member 34 and the projecting end ofthe pin 50. Therefore, the assembly 20 of beams 22 may be readily lowered with its longitudinal axis in a substantially horizontal position for an insertion into the warp knitting maching. As soon as the assembly 20 of beam 22 reaches the position indicated by the dash and dot lines 34" and 50", the lowering of the assembly will be stopped. Thereupon, the assembly 20 of beams is shifted in right hand direction as viewed in Fig. .3 for engagement of its coupling member 32 with the roller bearing 42 and for engagement of the coupling member 32 with the coupling member 32 of the assembly 20' if the latter'has been inserted first. Now,. the shiftable supporting member 88 is moved in right hand direction, until the collar bearing I08 mounted on its shoulder H0 abuts against the end of the brake end member 34 as shown in full lines in Fig. 3. As soon as the supporting member 88 reaches said position, the swingable latch I00 resting on the surface of the member 88 drops by gravity into the recess I 08, so that it holds the supporting member 88 in its engaging position. After the insertion of the assembly 20 of sectional beams 22 into the warp knitting machine as described above, the brake end member 34 of the assembly 20 is connected with thebeam brake I8 by attaching the gear segments 18 and 18 to the connecting member 54 by means of the screws 80.

Fora removal of the assembly 20 of beams 22 from the warp knitting machine the above described steps are carried out in reversed sequence.

In the drawingseach assembly of beams comprises three sectional beams. Of course, the assemblies of beams may be composed of any other suitable number of sectional beams.

Furthermore, a single beam instead of an'assembly of several beams may also be connected with the parts of the warp knitting machine according to above described principles of my invention.

According to the drawings the gear segments 18 and 18 for an operative engagement of the assembly of beams with the beam brake are attached to .the connecting member 54. If desired, the gear segments I8 and "I8could be secured to the assembly of beams in a different manner, for eigample they could be secured directly to the assembling member, if a different type of means for connecting the set of beams with the assembling member is used Moreover, the gear segments l8 and I8 may be replaced by other means for coupling the assembly of beams with the beam brake.

My invention is not restricted to the combination of parts shown in the drawings For example, the connecting means 54, 88 may be applied to an assembly of beams for use in a warp knitting machine which is not equipped with an axially slidable supporting member 88, 88 for the 'slidable supporting means 86, 88 for the support of a beam or anassembly of beams having a different type of connection with a beam brake than shown in the drawings. i
